My invention is more particularly designed for use in connection with the compositions for rendering paper transparent and increasing its electrical resistance. Such a composition is disclosed in a Patent No. 1,419,750 granted to me the 13th day of June, 1922. It is obviously desirable for the rapid handling of paper treated with the material in question,--that it drys asrapidly as possible after the treatment in order that it may be rolled up or otherwise formed into a compact bulk without the layers sticking together. It-is the purpose of the present invention to provide a drier which, when added to the composition of-t-he patent or similar compositions will cause the paper treat-ed therewith to dr rapidly so that it may be properly han led commercially in large quantities.

I prepare the drier in the following manner; I first mix four) ounces of acetone four (4) ounces of carbon-tetrachlorlde and approximately two easpoon s 0 commercial sodium silicate which normally contains abou y per cent (30%) of sodium silicate and seventy per cent (70%) water. The precise proportions given are not essential as any of the above described components may be substantially varied without departing from my inventlon in its broader aspect. These materials are well stirred together until thoroughly mixed and dissolved and then permitted to stand over night and decanted to free the mixture from the sedi-g ment which forms, or the material maybe strained through a close meshed filter;i';I separately dissolve four (4) ounces of a ve etable um such as rosin but preferably Blea Bed shellac in twelve. {12) ounces of acetone or other known solvent thereof. Kfter the gum has been thoroughly dissolved I let the mixture stand over night and then decant Orstrain it to freej it :oi sediment. The twoures are then poured together an ougy stirred and Application filed April 5,

The precise proportions o shel ac or o Tir gum to solvent are not material but those given have been found to be satisfactory. i I The resultant mixture may be added to "the patented composition infa wide range -0f--prop0r ti0ns, depending upon the nature of the paper to be treated and the desired effect. For thin apers which dry more readily I .have ad ed to the patented composition one-quarter of itsgweight of drier and where thick papers areto be treated,'I have added as much as one-half as much drier as composition to be dried. The most satisfactory amount for}; any particular paper can readily be determined by experiment. In case it is preferred that the paper dry more slowly, balsam um may be added to the drier. I have added balsam in -the proportion of one-twentieth by weight ito the drier with good results but the proportion thereof maybe varied within wide limits. j

I have found that with such additions to the composition-' for"*malcing "the paper transparent or insulating, thev paper treated therewith dries in a few moments after the ikompositioni has been applied thereto so '%that th'e'zla'yers thereof will not adherer to each other, vpermitting the paperto be continuously -nmwound from a troll, treated with the composition and rolled up again at a relatively rapid speed without the adherence of the layers to each other.
